Just under the frozen wasteland of the world's coldest continent are some seriously hot rocks, which are helping to melt its ice sheet and create lakes and rivers, a study found.

How hot? Try 1,800 degrees. The heat produced by the scorching hot rocks — officially known as a mantle plume — was measured at 150 milliwatts per square meter. That's not far from the heat produced under Yellowstone National Park, which is measured at about 200 milliwatts per square meter."
